The Holosun 509T footprint
Holosun 509T enclosed-emitter pattern. Unique tool-less clamp-style interface - the optic body has no top-down screw holes; instead a clamp-and-rail mechanism (similar in concept to ACRO but with different dimensions and NOT cross-compatible) attaches to a dedicated 509T cut or adapter plate. Ships in-box with an RMR adapter plate so it can be installed on RMR-pattern slides at the cost of added optical height.
